The main cloud services don’t even work natively (GoogleDrive, OneDrive, iCloud) basically the only mainstream choice is Dropbox. I tried to use Google Drive in Mint, and it’s a pain to get it to work, and usually it stops working after computer restarts.
Someone has a recommendation about how to handle these services?
GDrive has command line mount tools and works fine through rsync as long as you put the right tokens in the right places. Duplicity supports Google Drive as a backup destination, which is also quite useful for command line scripts.
Google doesn’t have any Linux clients other than their ChromeOS client, but there are plenty of tools that will synchronise your files.
